During this chemistry laboratory, students were given different solids and
solutions to experiment with, such as: aluminum, copper, glass, plastic, and wood, NaCl,
distilled water, tap water, ethanol, HCl, NH
, Gatorade, fruit punch and soda.
purpose of the experiment was to determine the electrical conductivity of the variety of
the given solids and solutions and to deduce what this means about the atomic-level
structure of these materials.
Aluminum, Copper, Glass, Plastic, Wood
0.1 M NaCl, 0.001 M NaCl, Distilled Water, 0.1 M Ethanol, 0.1 M HCl, 0.1 M
, Gatorade, Fruit punch, Soda
Large crystal of NaCl
Multi-well plastic Chemplate
Using the conductivity indicator, measure the conductivity of the given
solids, which are aluminum, copper, glass, plastic and wood.
these given solids are conductive or non-conductive.
Use the Multi-well plastic chemplate and fill the depressions with: 0.1 M
NaCl, 0.001 M NaCl, Distilled Water, 0.1 M Ethanol, 0.1 M HCl, 0.1 M
, Gatorade, Fruit punch, Soda.
Now use the conductivity indicator to measure each of the previous
solutions to determine if it is a strong, weak, or non-electrolyte.
